Abstract
Abstract A squeeze-to-release quick connector for engaging a flanged male member includes a cylindrical body portion which is open at one end for receiving the male member and forms a conduit receiving adapter at its opposite end. An annular retainer ring is axially spaced from the open end and is attached to the body portion by two circumferentially opposed, generally parallel axially elongated beam members. Each beam member is affixed at one end to the retaining ring and at an opposed end to a mount located on the body portion axially spaced from the open end. Two circumferentially spaced detents extend inwardly from a retaining ring to capture the male abutment surface to effect positive engagement therebetween.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
184 words
A squeeze-to-release quick connector adapted for selective locking engagement with a male member defining an outwardly extending abutment surface, said quick connector comprising: a generally cylindrical, elongated body portion open at one end for receiving said male member and forming a conduit receiving adapter at an opposite end; an annular retaining ring disposed concentrically with said body portion axially spaced from said open end; two circumferentially opposed, generally parallel, axially elongated beam members interconnecting said retaining ring and body portion, each said beam member affixed at one end thereof to said retaining ring and at an opposed end thereof to a mount located on said body portion axially spaced from said open end such that said beam members are radially spaced from said body portion; and at least two circumferentially spaced detents extending inwardly from said retaining ring to capture said abutment surface to effect positive engagement of said quick connector and male member, said retaining ring being adapted to be squeezed at angularly offset locations from said beam members to release said abutment surface from said detents for removal of said male member.
Claim 2
Dependent Claim
184 words

Claim 8
Dependent Claim
16 words
The quick connector of claim 6, wherein said female part is formed of injection molded plastic.
Claim 9
Dependent Claim
39 words
The quick connector of claim 1, wherein said retaining ring defines two circumferentially opposed gripping surfaces adapted to be squeezed to effect said release on an outer surface thereof angularly offset from said beam members by approximately 90 degrees.
Claim 10
Dependent Claim
18 words
The quick connector of claim 1, wherein said retaining ring and beam members are constructed of resilient material.
Claim 11
Dependent Claim
17 words
The quick connector of claim 1, wherein said detents are substantially angularly aligned with said beam members.
Claim 12
Dependent Claim
31 words
The quick connector of claim 1, wherein each said detent comprises a radially tapered ramp surface facing away from said body portion and an abutment surface facing toward said body portion.
Claim 13
Dependent Claim
20 words
